Hi, >From my squid (version below) a user visits microsofts site and tries to reach its virtual lab . AND this site redirects to other external sites. After a while the users screen starts to wait at connecting. When i look at the proxy log for the user i see that attemps are TCP_MISS and http and https (which the proxy gives service generally) and just last log entry is below . What does it mean , is there a problem with that site? Regards TCP_DENIED/400 1760 GET error:invalid-request - NONE/- text/html : squid Version : 2.6.STABLE21 Release : 6.el5
